Inhibition of ovarian cancer proliferation and invasion by pachymic acid.


PMID 25973134

Abstract

To determine the effect of pachymic acid (PA) on proliferation, cell cycle, and invasion in human ovarian carcinoma cell lines HO-8910 and explore some possible mechanisms, HO-8910 cells was treated with different concentrations of PA (0.5, 1, 2 μM). CCK-8 assay, propidium iodide staining, was applied to measuring the growth inhibiting rates of HO-8910 cells. Cell cycle was measured by flow cytometry. In addition, the activity of PA against HO-8910 cells invasion was evaluated in transwell assay. Western blot detected the proteins expression of E-cadherin, β-catenin and COX-2 of different groups treated with PA in different concentrations (0.5, 1, 2 μM) for 48 h. Our results showed that PA could effectively inhibit the in vitro growth of HO-8910 cells in dose-dependent manners in 72 h, suppressed migration and invasion of HO-8910 cells in concentration-dependent manners at 24 h, caused the increased accumulation of G1 phase cells, and caused down-regulation of β-catenin and COX-2 and up-regulation of E-cadherin expression level. Taken together, it could conclude that PA might inhibit proliferation and invasion of ovarian carcinoma cell through decreasing β-catenin and COX-2 expression and increasing E-cadherin expression.
